General description

Tangeretin is a polymethoxyflavone extracted primarily from the peels of citrus fruits like Citrus sinensis and Citrus reticulata.

Application

Tangeretin has been used as an antioxidant and antifungal agent to test its effects on ferroptosis inhibition, conidial development, and appressorium formation against Magnaporthe oryzae. It has also been used as a co-chemotherapeutics agent to study its cytotoxic effects in combination with 5-Fluorouracil (5-Fu) on WiDr colon cancer cells.

Biochem/physiol Actions

Tangeretin displays its anti-cancer effects by modulating different pathways in several cancer types in both in-vitro and in-vivo studies. It also exerts antioxidant, anti-inflammatory, and estrogenic properties.
Tangeretin is a flavonoid found in the peel of citrus fruits where it most likely provides natural resistance to fungi. Tangeretin has been shown to counteract tumor promoter-induced inhibition of intercellular communication and to inhibit cell proliferation in several cancer lines.

Semisynthesis of 5,3'-dihydroxy-3,6,7,8,4'-pentamethoxyflavone (1), a natural flavone that binds with high affinity to tubulin, was performed from hesperidin, the very abundant Citrus flavanone, by a five-step sequence. The last step of the synthesis also gave rise to 5,3'-dihydroxy-3,6,7,4'-tetramethoxyflavone (= casticin
